# Environment variables can be set directly in the configuration file.

# Using .kamal/secrets file to load required environment variables
|
||
#
|
||
# Kamal uses dotenv to automatically load environment variables set in the .kamal/secrets file.
|
||
#
|
||
# This file can be used to set variables like KAMAL_REGISTRY_PASSWORD or database passwords.
|
||
# You can use variable or command substitution in the secrets file.
|
||
#
|
||
# ```
|
||
# KAMAL_REGISTRY_PASSWORD=$KAMAL_REGISTRY_PASSWORD
|
||
# RAILS_MASTER_KEY=$(cat config/master.key)
|
||
# ```
|
||
#
|
||
# If you store secrets directly in .kamal/secrets, ensure that it is not checked into version control.
|
||
#
|
||
# To pass the secrets you should list them under the `secret` key. When you do this the
|
||
# other variables need to be moved under the `clear` key.
|
||
#
|
||
# Unlike clear values, secrets are not passed directly to the container,
|
||
# but are stored in an env file on the host

# Tags

# See kamal docs servers for how to tag hosts.
|

#
|
||
# Tags are only allowed in the top level env configuration (i.e not under a role specific env).

|
||
# The env variables can be specified with secret and clear values as explained above.
